Document Summary
Organic compounds are large carbon based molecules that carry out complex functions. They contain carbon, hydrogen and nitrogen and make up 38-43 percent of the human body. 55-60% of the human body is water and that decreases as you age. 2/3 of that is in the intracellular fluid, while the remaining 1/3 is in extracellular fluid. 80% of that is interstitial fluid and 20% is in plasma. Interstitial fluid is found between the cells: explain acids and bases in relation to the ph scale. The ph scale is done on a scale from 0-14. 14 being basic, 0 being acidic, and 7 being neutral. Acids; 0-7 substance that has more h+ than oh- dissociates into h+ anion (-) Buffers are the chemical compounds that can convert strong acids and bases into weak ones by removing or adding h+. This is important because strong acids can change ph drastically which can disrupt the body"s metabolism.
